I have some graphics algorithms that are drawn in red with dotted lines. I can see in the serialization that they aren't added that way, so it would appear to be some state that I'm causing at run time.

Is there something I may have done to these GraphicsAlgorithms that gets them drawn red? Is this an indication of some of of error state?

Graphiti uses this as visualization for an object that needs an update
because e.g. some changes in the domain world happened outside of the
diagram. They are caused by an update feature indicating updateNeeded =
true. So, you should check your update feature for that kind of domain
object.
